碘缺乏对儿童骨生长发育的影响

INFLUENCE OF IODINE DEFICIENCY ON BONE DEVELOPMENT OF CHILDREN

运用李果珍等骨龄百分计数法及判断骨发育程度的方法,对承德缺碘地区7～12岁非地方性克汀病(以下简称地克病)的健康儿童骨发育水平进行了调查分析,并选取晋县非缺碘地区同龄儿童进行对比观察。结果表明,前者儿童骨发育水平落后于非缺碘地区,骨发育落后儿童明显多于后者;缺碘地区有相当一部分非地克病的“正常”儿童骨发育轻度落后,碘缺乏影响了儿童骨胳的生长发育。

Applying Li Gozhen′s percenage estimation of bone age and the method of judging bone development levels, the authors surveied and analysed the bone development levels of 7-12 years old children without endemie cretinism in the iodine deficiency area(Chengde), and compared with cohorts residing in the iodine adequacy area (Jinxian Countiy). The results indicated that the bone development levels of children in the idine deficiency area was lower than those in the iodine adequacy area and the number of patients with dysostosis was much more than that in the iodine adequacy area. The survey shows that in the iodine deficieney area, most of normal children have slightly dysplasia for lock of iodine except the patients with endemic cretinism.
